About this Guide

This guide discusses the components and operation of the Extron VoiceLift System. For

details on installation procedures, see the VoiceLift System Installation Guide, part number

68-1629-01.

The following terminology is used in this guide:

• VoiceLift System refers to the entire system, which includes the pendant or handheld

microphones, the receiver, the charging station, and any secondary receivers.

• Receiver refers to the VLR 102 infrared (IR) receiver, which mounts onto a wall or

ceiling.

• Secondary receiver refers to the optional additional receiver (VLR 102SR). One

to three secondary receivers can be installed to expand coverage in a large or odd-shaped room.

• Charging station refers to the VLC 102 or VLC 202 charger for the microphone.

About the VoiceLift System

The VoiceLift System is a low-power classroom microphone amplification system that

enables a teacher or presenter to be clearly heard at a comfortable level throughout the entire room (also referred to as a “soundfield system”). The pendant or handheld microphone picks up speech from the teacher or student and transmits it via IR signal to the receiver. From the receiver, the signal is fed to an Extron PoleVault® switcher. The switcher functions as an amplifier and powers strategically placed speakers to improve the

signal-to-noise ratio of the voice of the speaker to at least +15 dB.

System Components

The VoiceLift System consists of the following components:

• Microphone (VLP 102 or VLH 102) — The pendant microphone (VLP 102) is worn

by the teacher or presenter on a lanyard around the neck. The handheld microphone

(VLH 102) is held by the student; it cannot be worn on a lanyard. Both microphones

feature volume control, a power switch, and an auxiliary line input connector to feed in a source (such as an MP3 player).

The pendant microphone also has an auxiliary input port to support an optional boom or lapel microphone. Pendant microphones can be hand held for use by students, if desired.

For descriptions of the two VoiceLift microphones, see “Microphones” in the “Features and Operation” section.

VoiceLift System • Introduction 1

• Receiver (VLR 102) — The receiver is the main sensor for the VoiceLift System. It

features the following:

• Captive screw connectors for auxiliary input, RS-232, contact input, and relay

output

• RJ 45 connectors for power, communication with the PoleVault switcher (which

functions as an amplifier), and audio output

• Two DIP switches that control the volume change tone and the output pin mode

• Secondary receiver (VLR 102SR) — The optional secondary receiver extends the

signal to cover large or odd-shaped rooms. It contains RJ-45 connectors for cables to the main IR receiver and to the PoleVault switcher. Up to three secondary receivers can be used with a VoiceLift microphone.

• Charging station (VLC 102 and VLC 202) — The optional microphone charging

stations contain slots in which one or two microphones can be placed for their batteries to be recharged. The charging stations are powered by an external power supply.

The two charging stations are identical in function except that the VLC 202 slots can accommodate the VLH 102 Handheld Microphone, while the VLC 102 slots cannot.

Their design and appearance are slightly different as well.

CAUTION: Do not charge alkaline batteries.

Features

The VoiceLift System features the following:

• Lightweight microphones — The pendant and handheld microphones are made

of lightweight and impact-resistant polycarbonate material. The pendant microphone can be worn comfortably around the neck or clipped to clothing.

• Built-in DSP feedback suppression — The receiver has an integrated Digital

Signal Processor (DSP) that suppresses feedback while maximizing sound quality and intelligibility. The DSP prevents ringing due to frequencies cycling out of control through the microphone and speakers.

• Two microphones per classroom — The VoiceLift System supports up to two

pendant microphones, or one pendant and one handheld microphone, in each classroom. The pendant microphone can be used by teachers and students, as desired (it is recommended that the handheld microphone be used by students).

• Power (Mute) buttons — The microphones contain easily accessible buttons on the

sides or front to mute the sound and power the microphone on and off.

• Volume buttons — On the pendant microphone (normally used by the teacher or

presenter), a Volume button is conveniently located on the side, enabling the teacher

to easily raise and lower the volume during a presentation.

On the handheld microphone (normally used by the student), Volume Up and Down

buttons are located behind the battery cover. These buttons can be used to set the volume prior to use, but cannot be accidentally pressed by the students during the presentation.

• Instant alert e-mail messaging — The VoiceLift receiver can be wired to enable

the teacher to send e-mail alerts by pressing the microphone Volume button when assistance is required.

• Auxiliary line input — An auxiliary input connector on the microphone enables

input from an MP3 player or other source.

VoiceLift System • Introduction 2

• Battery power — The VLP 102 and VLH 102 microphones are each powered by a

FF 120 Speakers

single NiMh or alkaline AA battery. NiMh batteries can be recharged via the VLC 102 or VLC 202 charging station or by a wall charger.

CAUTION: Do not charge alkaline batteries.

• Charging station — The VLC 102 and VLC 202 desktop charging stations each hold

and recharge up to two VoiceLift microphones simultaneously.

• Mounting options — The VLR 102 receiver is compact and can be mounted on a

wall or ceiling, or to a junction box.

• Expandable coverage — The optional VLR 102SR secondary receiver provides

expanded coverage for large or odd-sized rooms.

station, insert the end of the microphone containing these contacts into one of the charging slots.

Handheld Microphone

The VLH 102 Handheld Microphone can be used with the VoiceLift System as an alternative to the VLP 102 Pendant Microphone. The VLH 102 is best used as a

pass-around microphone for student presentations or a secondary microphone for team teaching and guest speakers.

The handheld microphone has many of the features of the pendant microphone, including a power switch and an auxiliary input jack to allow playback from audio devices through the system. It is powered by one AA-sized battery that can be recharged in the microphone

via an external wall charger or the VLC 202 Charging Station.

NOTE: The VLC 102 charging station cannot be used to charge the VLH 102 handheld

microphone.

The VLH 102 provides two channels: channel A at 2.3 MHz and channel B at 2.8 MHz. Unlike the VLP 102, it does not provide channels C and D for disabling the volume control

on the student microphone, nor does it have a microphone input jack for connecting an additional microphone.

Tips for Using the Microphones

Receiver

• Speak in a normal tone of voice. When the microphone is set properly, your voice is

amplified above ambient room noise.

• Turn the microphone off while having private conversations.

• Charge the microphone battery every night. A fully charged battery will last the entire

school day.

NOTE: Always turn the microphone off before charging.

• If you are experiencing intermittent audio problems:

• Check the batteries and replace them if necessary. NiMH and alkaline batteries are

supported.

CAUTION: Do not charge alkaline batteries.

• Do not use more than one microphone on a channel.

• Make sure there are no obstructions between the microphone and the receiver.

The VoiceLift VLR 102 Receiver receives infrared signals from the VoiceLift VLP 102 Pendant Microphone. The receiver outputs a balanced -10 dBV line level signal via an RJ-45 connector.

Integrated DSP

DSP is a specialized circuit that processes audio signals that have been converted to digital

form. The VLR 102 Receiver has a built-in DSP that suppresses feedback while maximizing

sound quality and intelligibility.

As feedback occurs, up to 15 dynamic filters engage, automatically detecting and

eliminating unwanted feedback frequencies. The dynamic filters are notch filters, providing

up to 30 dB of attenuation for feedback frequencies caused either by high microphone

levels, room resonance, or proximity of the microphone to a speaker.

The DSP retains a maximum of 10 filters. After a period of 2 minutes, if the number of filters is greater than 10, the oldest filters begin to slowly release until the number of dynamic filters in use equals 10. This process assures that five filters are always available in

case of unexpected feedback. See the VoiceLift System Installation Guide for the procedure to set the dynamic filters.

c DIP switches

• Mix switch — Selects the output mode of the receiver.

• When the switch is set to Off (down), the receiver outputs microphone and

auxiliary input audio on separate pins. This is the default state for the Mix switch.

• When the switch is set to On (up), the microphone audio is mixed with

the auxiliary input audio. The receiver then sends mixed output on the

microphone line to the PoleVault switcher.

NOTE: Do not set the Mix switch to On unless there is an input source

connected to the Aux input jack. Noise may be introduced into the system if no source is connected when the Mix switch is enabled.

• Tone switch — Enables and disables the tone generated when the microphone

volume changes. As the microphone volume increases, the level of the tone increases also. The default state for this switch is On.

d RS-232 configuration port — This port allows firmware upgrades and gain

adjustments to be performed via SIS commands (see the “SIS Configuration and

Control” section). An IP Link device can be connected to this port to monitor the

status of the receiver. The default protocol for this port is:

• 38,400 baud • No parity

• 8 data bits • No flow control

• 1 stop bit

e Auxiliary input (Aux In) port — Connect a mono auxiliary input device, such as an

intercom, to this three-pole captive screw connector.

For example, this port can be connected to an IPI Intercom for an instant alert application. In this configuration, the Mix DIP switch is set to On to mix the microphone audio when a message is streamed from a help desk.

NOTE: Volume on an auxiliary input is not affected by the microphone volume

control.

f Contact input (CTC) port — Connect this two-pole captive screw connector to a

contact closure device such as a pushbutton or a motion sensor.

g Relay (Rly) port — This relay port allows control of items such as lighting. If

connected to a Digital I/O port of an MLC control panel, this port can be used to set up an instant alert (see the “Special Application” section).

The default state for this Relay port is normally open. To trigger the relay, hold

down both parts of the Volume rocker button on the pendant microphone, or hold down both Volume buttons on the handheld microphone, simultaneously for 3 seconds. When the relay is closed, the LED in the center of the receiver dome

flashes, alternating between amber and green. The relay returns to an open state

10 seconds after the Volume buttons are released. The contact rating for this port is 24 V, 1 A.

NOTE: The microphone must be on channel A or B for the Volume buttons to

trigger the relay.

• Overview

• Host to Receiver Communication

• Commands and Responses

• Command/Response Table for SIS Commands

Overview

The VoiceLift VLR 102 receiver can be controlled via a host computer that is connected to the RS-232 control port on the receiver. You can issue the SIS commands via the RS-232 interface on the computer, using a communication software program such as HyperTerminal or the Extron DataViewer. SIS commands are available for you to do the following:

• Upload firmware

• Obtain information and status for VoiceLift ports and system components

• Adjust the volume for a specific channel

Default protocol for the VoiceLift receiver RS-232 port:

• 38400 baud • 1 stop bit

• No parity • No flow control

• 8 data bits

Host to Receiver Communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the VLR 102 determines that a command is valid, it executes the command and sends a response to the host device. All responses from the receiver to the host end with a carriage return and a line feed (CR/LF = more characters.

Additional messages may be sent by the VLR 102 in response to changes in the contact

closure input state, relay state, or microphone channel selection.

Error response

When the VLR 102 receives a valid SIS command, it executes the command and sends a

response to the host device. If the receiver is unable to execute the command because the command is invalid or contains invalid parameters, it returns the following error response to the host:

E13 – Invalid value (the number is out of range)

control panel. Topics included are:

• Setting Up an Instant Alert

• Applications Diagram

Setting Up an Instant Alert

A useful application for the VoiceLift System is the instant alert. By connecting an MLC 104 IP Plus control panel to the relay port VLR 102 Receiver, you can set up e-mail

alerts to be sent out when both parts of the microphone Volume button are pressed and held for 3 seconds.

NOTE: This is not a “life safety” feature because it depends on line of sight or

reflection to the receiver.

To set up an instant alert, follow these steps:

1. Wire one of the provided two-pole captive screw connectors to one end of a

communication cable.

2. Insert the red wire in the left slot of the connector and the black wire in the right slot.

3. Plug the communication cable into the receiver Rly (relay) port. Ensure that the red

wire is connected to the NO (normally open) port and the black wire is connected to the C (common) port.

Connector to MLC Control Panel

Figure 30. Communication Cable Connected to the Receiver Relay Port

VoiceLift System • Special Application 33

NOTE: If the MLC and the PoleVault switcher are using separate power supplies,

ground the C pin of the receiver Rly port to the receiver using a jumper between the C pin and the ground (_) pin on the contact input (CTC), the auxiliary input (Aux In), or the RS-232 port.

Figure 31. Jumper Wire Connecting the Receiver Relay Port Common Pin

with the Ground Pin of the Contact Port

4. Pull the communication cable to the MLC 104 IP Plus and insert it into one of the MLC

direct-insertion Digital I/O ports as follows:

Room factors to be considered should include, but are not confined to:

• Interference and noise sources

• Line-of-sight obstructions between microphone and receiver

• Reflective surfaces

• Location of the VLR 102 receiver

• Best location is on the ceiling, at the middle of the classroom.

• If ceiling mounting is not possible, place high and centered on the longest wall.

• Locations to avoid:

• Places where line of sight could be obstructed; for example, too close to the

projector

• Corners of the room

• On walls, at less than 6 feet (1.8 m) or more than 12 feet (3.6 m) up from the

floor

• Areas that receive direct sunlight

• Need for optional VLR 102SR Secondary Receiver

One or more secondary receivers (VLR 102SR) may be needed if:

• The room is larger than 35 feet (10.6 m) by 35 feet (10.6 m).

• Obstructions exist between the microphone and the receiver.

• The room is odd-shaped; for example, L-shaped or long.

• The room has recessed or sheltered areas, such as alcoves or bays.

• The room has large windows or windows on multiple walls.

• Portions of the walls are dark or covered. Dark surfaces reduce signal reflection.
